Subject:	Please fork soft-fp from libc

Hello!

There was no response from libc maintainers about changing the type of
soft-fp compares into CMPtype. This type should be defined to mode(word)
or at least we should be able to redefine it outside the soft-fp, in
target dependent sfp-target.h. As this is major obstacle in further
development (complex numbers) and even in the usability of software FP
as part of gcclib (TFmode compares return wrong values), I propose that
we fork soft-fp from libc. Soft-fp already diverged from libc by
inclusing TImode and TFmode conversions.

Otherwise, I propose that we disable TFmode support on x86_64 due to
above problems with compares.

Thanks for considering this,
Uros.
